Abstract
A new cathode is described consisting of an oxide-impregnated nickel matrix. A sintered nickel matrix of controllable porosity is prepared and impregnated with solutions which precipitate a mixed carbonate within the matrix. The resulting cathode is a dispenser type with a minimum of surface coating. The cathodes can be activated by schedules which approximate those of a normal oxide-coated cathode. Pulse-emission tests of these cathodes show properties intermediate between the oxide-coated cathode and the L-cathode, and of the same order as the molded cathode described by McNair, Lynch, and Hannay.This publication has 4 references indexed in Scilit:
